OSCILLA'IING FAN.

Specification of Letters Patent.

Application filed March 24, 1909.

Serial No. 485,465.

To all whom it may concern:

Be it known that I, lit-amino) A. S'rown, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improrement in Oscillating Fans, of which the. following is a specification, the principle of the invention being herein explained and the best-mode in which I have contemplated applying that prim-iple, so as to distinguish it from other inventions.

'l'he superioritr of an oscillating, over a simple stationary. fan for the purpose of cooling and 'ctlecting a circulation of the air in t)tl'l('(' and other rooms, is well recognized. ("ousiderable difficulty has been encountered. however. in providing positive means for \tiltl'lllg such oscillation while still permitting adjustment of the fan, so aslo enable the current of air excited thereby to be din-vied in any desired direction. or rather plane.

The object of the present invention, is the prmisiou of a fan, that, while positively oscillated, is nevertheless susceptible of su h adjustment, and in addition is adapted for use either resting on a table, desk or like horizontal support, or secured to a vertical support, as a wall.

Po the accomplishment of these and re lated ends, said invention, then. consists of the nueans hereinafter fully described. and particularly pointed out in the claims.

The annexed drawings and the following description set forth in detail certain mccbanism embodying the invention, such disclosed means onstituting, however, but one of various mmrhanical forms in which the principle of the invention may be. used.

In said annexed drawings:--Figure 1 is a side elevation of an improved construction of electrically driven fan embodying my HVtltll imprm'enu-nts; l igs. .5 and 3 respectively illustrate on a smaller scale thematiner of mounting said ,fan on a horizontal and on a vertical support; Figs. 4 and 5 are front elcnttional views of the frame eonstituting a feature of the construction of my. improred fan in different operative positions respectively; while Figs. (3 and 7 are imilarly horizontal sectional views of said support, showing certain parts in different operative positions respectu ely.

The base A of the fan, to which the leads for conducting current to the fan motor are attached, and wherein is included a suitable switch device, may take on any form, ornamental or otherwise that' the fancy of the designer may direct. Said base is adapted, however, as shown in Figs. 2 and 3, either to rest upon a horizontal support or to be secured by screws or the like to a wall or other vertical support. Said base is further provided with an undercut slot a forming a seat and adapted to receive a curved support B wherein the fan C proper is mounted. The support B is substantially semi-circular in form, and is formed on its outer face with arib slidably fitting such seat a and on its inturned face with a groove or way 0 constituting a guide for a purpose that will be presently dcsxrribed. In conjunction with the seat a. in the base, set-screws a or like clamping means are provided, whereby said semicircular support may be secured at any desired point about its periphery, effecting a correspomling change in its an ular incline tion and in the position of the fan C carried thereby.

The casing of the fan motor,in the present instance an electric motor, (shown as an alternating current motor in Fig. 1, and as a direct current motor in the remaining ti ures of the drawings), is pivotally held 111 support I by pins (1' a'liued with a diameter of the circle to which the support, am ltl1e way I) formed therein, conform. The axis of the motor shaft upon the forward end of which iamounted the fan a proper likewise coincides irith a diameter of said circle at right angles'to such first diameter. Upon the end of the casing opposite the fan, which end freely moves across the support I! is totatalily mo'unted an arm 0" that is curved to lie close to the way or inturned face of the support when aliued therewith. Said arm is connected to be rotated by the same motor shaft 0, upon the forward end of which is mounted the fan, and, since the latterwill ordinarily require to be driven at a higher rate of speed than is desirable for the rotation of this arm (having in view its function, which will now be explained) suitable reduction gearing c", is interposed between the shaft and the arm. This gearin may obviously take on any form adopted or the suit of such eccentric connection, rotation of the arm, will he obviously efi'ective to impart an oscillatory movement to the motor casin about its own pivotal axis.- Figs. 4 to 7, inclusive, will it is thought, clearly indicate the character of the movement thus secured. In Figs. 4 and 6, the arm is vertically disposed, that is alined with support 13 just as in Fig. 1, while in Figs. 5 and 7 such arm ap ears horizontally extended to one side of t e support. A In a complete rotation, of course it assumes, in addition to these positions, an upwardly extending vertical position and a horizontal position in which it extends oppositely to that shown in the last named figures. As said arm assumes such respective horizontal positions the rear end of the motor casing is of course laterally displaced, or rather oscillated, as will be readily understood. Not only is the oscillatory movement of the fun casing a positive one, but a quiet and easy one as well, while the amplitude of the are throu h which such oscillation takes place may e readily varied by adjustment of the pin 0, wherewith engagement between the arm and the way I) is secured. It will be equally clear that this oscillation will not be interfered with by any variation in the angular disposition of the support B in the seat pr r vided therefor in base A, nor by the location of the latter, whether on a vertical or horizontal support.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means is employed.
